Urea minimizes the change in the acid/base balance of a product when other ingredients are added to that product. It also slows the loss of moisture from a product during use. When used in the formulation of skin care products, Urea increases the water content of the top layers of the skin.
This term means “water-loving”, which gives urea its amazing ability to hold onto water molecules, keeping your skin plump and moist.
One of the many ways urea benefits your skin is strengthening and protecting the barrier function and keeping it healthy.
At higher percentages within a formula urea becomes a natural keratolytic (exfoliator).
Urea improves your skin’s health by metabolising the antimicrobial peptide LL-37, which attacks acne-causing bacteria within the skin.
